Prosecutors are portraying Gilbert Arenas as a thuggish intimidator who tried to pressure his teammate into a cover-up, as they argue for a three-month jail sentence for the NBA star on a weapons charge. Arenas' lawyer says his client is "a peaceful man" who played a misguided prank and has already been severely punished for bringing guns into the Washington Wizards locker room. He says the more fitting punishment is probation and community service. Both sides staked out their positions Tuesday in court filings, ahead of Friday's sentencing in D.C. Superior Court. Arenas pleaded guilty Jan. 15 to one felony count of violating the District of Columbia's strict gun laws, a charge stemming from a locker-room confrontation that followed a card-game dispute between Arenas and teammate Javaris Crittenton during a Dec. 19 flight.
